A. Several products on the market can be used to change the color of asphalt shingles, but the color choice is limited. There are both acrylic and elastomeric coatings, but they are usually restricted to black, white, and gray in color. White can be tinted to a pastel color by adding pigments, but no other dark colors are available. Elastomeric coatings are available from Kool-Seal (1499 Enterprise Pkwy., Twinsburg, OH 44087; 800/321-0572) or Macklanburg-Duncan (M-D, 4041 N. Santa Fe, Oklahoma City, OK 73118; 800/654-8454). M-D also makes acrylic roof coatings that might be used. Whatever you choose, check first to see whether or not the coatings will void the manufacturer’s warranty on the shingles.
